External Air Temperature Sensor

[fishugo]

Last winter after registering accurately -40 F in the Adirondacks, my outside temperature readout has gone into serious denial and wants to tell me the outdoor temperature is in the 50's no matter what time of year.

Is there any way to reset this thing? Does anybody know the real name of the sender mounted in front of the radiator?

Here in New England it is useful to know the outdoor temp so you can be aware of black ice and that sort of stuff. So if it can't be reset, maybe I could replace it if I had a part ID or number. Any ideas?

Ambient air temp sensor.....the parts department might call it something a little different. These sensors are the most common problem I have come across when the display is inaccurate.

I have an 02 explorer that reads from 99 - 102 all the time. Does it sound like an sensor error or a ground problem?

Where is the sensor located? How hard is it to change?

 

[Michigander]

ok, I found the senser... behind the front grill... remove grill and it is right there... sweet

part #19E702 -- Ambient temperature sensor

Looking to replace mine, I live in the UK, so I had have my father swing by the local dealership and this part number didn't come up.

I would have figured they could look up a solution at the dealership and they sent my dad away with no info...

If you remove the grille, check for the screws on top, it should be on the passenger side.


I will take some pics tomorrow and post up. Too late to do it now.

 

[BigRondo]

forcemac, did you get it installed? I should have some pics up in about an hour! Sorry for the delay. The thread got buried and I just remembered that I was supposed to post up some pics.

How To: Replace 3rd Gen Ambient Air Temperature Sensor

Good write up - thank you! Mine is screwy also - it usually displays "--", but today it actually displayed 140. Since it's early February in Chicago, I realize that was false. I am finding conflicting part numbers though. Where do you guys recommend getting it from? Besides the ford dealer because I REALLY don't like going through dealers. Here's a link I found with three different choices on it, but which is correct?

Here are a couple links I found that say they are both the ambient temp sensor for an 04 explorer, but they replace different oem parts. Interesting...

EDIT: apparently it didn't like that super long link, so here's the second one, shortened. http://tinyurl.com/6k5ukz5

I recommend the dealer, www.rockauto.com or www.silverstatefordparts.com. If you go with Rock Auto, be sure to get the discount offered to EF members.

I don't know if they changed the part for the later years, but the one pictured in the your links look nothing like mine:

Dang I was hoping no one would see my post pre-final editing haha. Anywho, in the link in my final edit (http://www.drivewire.com/vehicle/2004-ford-explorer/ambient-temperature-sensor/) the top one sort of looks like that...

Ok can't find it on either of the links you posted, what part # would I search for on them?
